Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit ultra-low-power MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GLG2DFB#AA0 | 64-pin LFQFP, 128 KB flash, 16 KB RAM - identical memory and core, but 16 fewer I/O pins and no CTSU2L support | Limited to simpler HMI or control tasks without touch sensing or high peripheral count | Select when board space or cost constraints favor smaller package and touch capability is unnecessary |
| R7F100GMH2DFB#AA0 | Same 80-pin LFQFP package, but 192 KB flash and 20 KB RAM - higher memory capacity with identical peripheral set and power profile | Required for larger firmware images (e.g., OTA update stack, advanced encryption, or multi-protocol stacks) | Choose when application firmware exceeds 128 KB or requires additional RAM for buffering or RTOS heap |
Compared with R7F100GLG2DFB#AA0, the R7F100GMG2DFB#AA0 adds 16 I/Os and CTSU2L for touch interfaces; compared with R7F100GMH2DFB#AA0, it trades 64 KB flash and 4 KB RAM for lower cost and footprint while retaining full peripheral functionality for mid-complexity designs.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GMG2DFB#AA0?
The R7F100GMG2DFB#AA0 operates up to 32 MHz using the high-speed on-chip oscillator, with guaranteed functionality across its full 1.6–5.5 V supply range. At 32 MHz, the minimum instruction execution time is 0.03125 µs. The device maintains full peripheral operation-including ADC, RTC, and CTSU2L-at all supported frequencies and voltages, with no derating required.
Does the R7F100GMG2DFB#AA0 support hardware-based capacitive touch sensing, and what configurations are available?
Yes, the R7F100GMG2DFB#AA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) supporting both self-capacitance (up to 32 keys on single pins) and mutual capacitance (8×8 matrix, up to 64 keys). It includes built-in noise cancellation, auto-calibration, and dedicated hardware acceleration - eliminating the need for external touch controllers or software-intensive polling routines in the R7F100GMG2DFB#AA0 design.
What low-power modes are available on the R7F100GMG2DFB#AA0, and what is the lowest achievable current draw?
The R7F100GMG2DFB#AA0 offers HALT, STOP, and SNOOZE modes. In STOP mode with 4 KB RAM retention enabled, it achieves 210 nA typical current draw. SNOOZE mode allows autonomous peripheral operation (e.g., ADC sampling, comparisons) at ~1.2 µA average current - significantly lower than full CPU wake-up - making the R7F100GMG2DFB#AA0 ideal for battery-powered sensing applications with infrequent wake events.
Can the R7F100GMG2DFB#AA0 perform background data flash writes while executing code from main flash memory?
Yes, the R7F100GMG2DFB#AA0 supports Background Operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously rewriting data flash - essential for reliable firmware updates, parameter logging, or secure key storage without halting real-time application logic in the R7F100GMG2DFB#AA0 system.
What is the purpose of the REGC pin on the R7F100GMG2DFB#AA0, and how must it be connected?
The REGC pin on the R7F100GMG2DFB#AA0 is the regulator capacitor terminal for the internal LDO. It must be connected to VSS via a 0.47–1 µF ceramic capacitor placed as close as possible to the pin. Failure to properly decouple REGC will cause unstable internal voltage regulation, leading to erratic reset behavior, flash programming errors, or failure to enter low-power modes - a mandatory layout requirement for functional R7F100GMG2DFB#AA0 operation.
